Chris Lattner fd1ad10e61 shave another 150K off of kc++, by using a 7-bit encoding for BB names 
where we can.  This shrinks kc++'s down to 3368K, with a VST record of:

  Block ID #14 (VALUE_SYMTAB):
      Num Instances: 2345
         Total Size: 1.29508e+07b/1.61885e+06B/404713W
       Average Size: 5522.73b/690.342B/172.585W
          % of file: 48.0645
  Tot/Avg SubBlocks: 0/0
    Tot/Avg Abbrevs: 7035/3
    Tot/Avg Records: 120924/51.5667
      % Abbrev Recs: 100

Isn't it nice to be able to optimizer bc size without touching the reader? :)

Chris Lattner 4d92598ab0 where possible, encode symtab names with 7 bits per char instead of 8. This 
shaves 110K off kc++ to 3514K.  Before:

Chris Lattner 2eae59f1c1 Encode all value symtab strings as arrays of 8-bit fixed width integers, 
instead of the default inefficient encoding.  This shrinks kc++ from 4134K

Chris Lattner 430e80d670 optimize constant layout. This fixes encoding of 181.mcf (by ensuring 
integer structure idx's are emitted before constant expr geps) and shrinks
files slightly.  For example kc++ shrinks from 4326188 to 4240128 bytes.

        %tmp5 = bitcast <2 x i64> %x to <8 x i16>               ; <<8 x i16>> [#uses=1]
        %tmp = add <8 x i16> %tmp5, %tmp4               ; <<8 x i16>> [#uses=1]
        %tmp6 = bitcast <8 x i16> %tmp to <2 x i64>             ; <<2 x i64>> [#uses=1]

 2007-04-29 20:56:48 +00:00
Chris Lattner 6694f60bec Switch the bitcode reader interface to take a MemoryBuffer instead of knowing 
anything about disk I/O itself.  This greatly simplifies its interface -
eliminating the need for the ReaderWrappers.cpp file.

This adds a new option to llvm-dis (-bitcode) which instructs it to read
the input file as bitcode.  Until/unless the bytecode reader is taught to
read from MemoryBuffer, there is no way to handle stdin reading without it.

I don't plan to switch the bytecode reader over, I'd rather delete it :),
so the option will stay around temporarily.
